Note 1 to entry: Rubia is a genus of flowering plants in the Rubiaceae family. The genus and its best-known species are commonly known as madder, e.g. Rubiatinctorum (common madder), Rubiaperegrina (wild madder),
and Rubiacordifolia (Indian madder). The plant’s roots contain an anthraquinone compound called alizarin that gives red colour to the dyed textile. Rubiacordifolia contains more of anthraquinonesmunjistin and purpurin.expressing of colours to textiles by dyeing or printing.colourant obtained from plants, wood, rocks, soil, insects or any other thing existing on earth without any chemical reaction adopted before colouring of textiles.Dilute the concentrated extract with water and methanol to a concentration of approximately 100 mg/l.Filter about 1 ml of the diluted solution into a HPLC vial using disposable syringe equipped with a membrane filter (6.5).The detection and qualification of alizarin is conducted using LC-MS [6.6) with ESI mass spectrometer. The recommended chromatographic conditions are given in Annex A.Comparison between analyses of standard and sample through Z.3 may show the result of existence of alizarin in sample.Detection of alizarin may vary due to conditions of coloured sample. In this case, the amount of specimen and extraction solution can be modified, and concentration of extracted solution can be adopted. The modified sample preparation conditions should be described in test result.BS ISO 22195-1 pdf download.
